Answer:

42

Step-by-step explanation:

Find the prime factorization of 126

126 = 2 × 3 × 3 × 7

Find the prime factorization of 420

420 = 2 × 2 × 3 × 5 × 7

To find the GCF, multiply all the prime factors common to both numbers:

Therefore, GCF = 2 × 3 × 7

GCF = 42

astraxan [27]

Answer:

1) El helado costó $135,65.

2) a) Gastó en total $487,5. b) Le dieron $112,5 de vuleto.

Step-by-step explanation:

1) Podemos encontrar el costo del helado como sigue:

T = J + A + H

H = T - J - A = 250 - 28,85 - 85,50 = 135,65

Por lo tanto, el helado costó $135,65.

2) a) Para saber cuanto dinero gastó debemos sumar todos los precios:

T = B_{p} + B_{g} + P = 349,50 + 108,25 + 29,75 = 487,5

Entonces, gastó en total $487,5.

b) Si pagó con $600, su vuelto fue:

V = 600 - T = 600 - 487,5 = 112,5

Le dieron $112,5 de vuleto.

The number of bacteria present in a culture after t minutes is given as b=1000e^kt where k is a constant. If there are 8520 bact
Kryger [21]

To solve this problem, plug 8250 in for b and 15 in for t and then solve for k:

8250=1000e^{15k}

<em>*Divide both sides by 1000*</em>

8.25=e^{15k}

<em>*Take the natural log (ln) of both sides*</em>

2.1102=15k

<em>*Divide both sides by 15*</em>

0.1406=k


0.1406 rounds to 0.141 which is close to a. 0.143.


Hope this helps!!
